Left rear of vehicle started making a crunching/rattling noise over even the slightest bump. Dealership determined it to be noisey swaybar link. This happened because bushing pushed out apparently. They had to install a washer on swat bar bushings retainer. Not sure if this could have been a potential safety hazard where I could of lost control of vehicle. I found this bad because car is new and only 2 months old and I drive all highway interstate miles. No side/off roads with major bumps to knock this out. Hopefully prob won't happen again. It is a concern since veh is new and there was no extremely rough driving done with vehicle.
